Free Editable Fault Tree Analysis Diagram Examples

Back in 1962, H Waston and A Mearns developed the fault tree analysis in Bell Laboratories. Several tools are there that help identify potential failures, their mechanism, and causes. The fault tree diagrams are tools like these. Fault Tree analysis is a deductive analysis that depicts a visual path of failure. Potential failures, if detected early, can help mitigate the risk. It saves consumers from an untoward experience.

1. What Is a Fault Tree Analysis Diagram

A fault tree helps to depict a failure chain or path. The fault tree analysisfollows the Boolean logic concept that creates true or false sentences. If one links the statements in a chain, they develop a logic diagram of failures. The events arrangements are there in series or parallel relationships. People use logic symbols to mark dependencies among events.

If one can mitigate the risk before the program launch, it helps him in numerous ways. For example,

  • If one analyses the hazard beforehand, he builds a safety corner for himself.
  • He can find new content with innovative designs.
  • With minor modifications, one may include changes to the past failure.
  • One can investigate the regularity or safety concerns.
  • The pictorial representation is always better than a written inductive analysis.

Fault tree diagrams are not hard to make. By following some basic steps, one can easily create them.

  • At first, one needs to identify the hazard.
  • Next, he must obtain some understanding of the system that he is analyzing.
  • Now, it is time to create the fault tree.
  • He can identify the cut sets.
  • Lastly, he must mitigate the risk.


2. The Fault Tree Analysis Diagram Examples

People use fault tree analysis in automobile, aerospace, nuclear, chemical, and software industries. They help in the risk assessment processes. One can use it to solve complex systems and logically identify problems. The fault tree highlights the critical components. By analyzing methods, one can prioritize the action items to solve a problem. It is a must use for qualitative and quantitative analysis.




Example 1: Fault Tree Analysis Diagram

The given fault tree is an audit-failure fault tree diagram, which helps analyze why an audit fails to perform. The example depicts how the result of the audit failure can lead to system failure. Any undesirable event can happen in an organization at any time. It is helpful to analyze the origin with a fault tree analysis.

One can take help from an online fault tree diagram maker like EdrawMax to make his own.
